Executive brief
Raneto is an open-source documentation platform that stores sensitive knowledge and configuration data. Version 0.17.0 accepts weak passwords that do not enforce sufficient complexity requirements, making user accounts vulnerable to brute-force attacks. An attacker can guess user passwords through automated attempts, potentially gaining unauthorized access to documentation and internal information.
Technical details
The vulnerability is a weak password policy implementation (CWE-521) in Raneto v0.17.0 that fails to enforce adequate password complexity requirements. This allows attackers to conduct brute-force attacks against user accounts without the protective barrier of strong password requirements. The vulnerability requires network access to the Raneto instance and no authentication, as an attacker can attempt password guesses at the login endpoint. Successful exploitation grants an attacker access to the targeted user account and all associated data and functionality. The issue was patched in version 0.17.1.
